%% 
%% 1. Documentation: how to compute the values of various variables;  
%%    
%% 2. Definition of auxiliary functions and data (e.g., colors);
%% 
%% 3. Drawing data.
%% 
%% 
%% 1. DOCUMENTATION
%%
%% In the following, names of variables are UPPER-CASE, while
%% 2d points are denoted between squared ([,]) parentheses
%%
%% We need to set the values of only 3 variables:
%%
%% 1. OUTER-RADIUS <--- from ``outercircle'' file
%% 2. FRAME-ALLOWANCE (to put some space between the bounding box and
%%                     the diagram. Suggested value 1.1)
%% 3. HALF-FRAME (size of half the bounding box, in postscript
%%                points. Suggested value 3000)
%%
%% Now all the other auxiliary variables are set as it follows:
%%
%% EPS-SCALE = 300.0 / HALF-FRAME
%% 
%% CENTER = [HALF-FRAME,HALF-FRAME]
%% 
%% SCALE = HALF-FRAME / (OUTER-RADIUS * FRAME-ALLOWANCE)
%% DIAGRAM-LINEWIDTH = CEILING (HALF-FRAME / 1500)
%% AXES-LINEWIDTH = CEILING (HALF-FRAME / 3000)
%%   
%% AXES-FONTSIZE = CEILING (HALF-FRAME / 15)
%% DIAGRAM-FONTSIZE = CEILING (HALF-FRAME / 20)
%%   
%% AVERAGE-DIRECTION-COLOR = 1 (blue)
%% DIAGRAM-COLOR           = 4 (red)
%% CIRCLE-COLOR            = 2 (green)
%% AXES-COLOR              = 0 (black)
%%   
%% NORTH-JUSTIFICATION = 2
%% EAST-JUSTIFICATION  = 6
%% SOUTH-JUSTIFICATION = 8
%% WEST-JUSTIFICATION  = 8
%%   
%% NORTH-X-SHIFT = 1.02 * HALF-FRAME
%% NORTH-Y-SHIFT = 1.98 * HALF-FRAME
%% EAST-X-SHIFT  = 1.98 * HALF-FRAME
%% EAST-Y-SHIFT  = 1.02 * HALF-FRAME
%% SOUTH-X-SHIFT = 1.02 * HALF-FRAME
%% SOUTH-Y-SHIFT = 0.02 * HALF-FRAME
%% WEST-X-SHIFT  = 0.01 * HALF-FRAME
%% WEST-Y-SHIFT  = 1.02 * HALF-FRAME
%%   
%% ALL-DATA-STRING          = "All Data (NULL included)"
%% REAL-DATA-STRING         = "Real Data Angles"
%% AVERAGE-DIRECTION-STRING = "Avg. Direction"
%%   
%% LEGENDS-X                   = 1.95 * HALF-FRAME
%% ALL-DATA-LEGEND-Y           = 1.95 * HALF-FRAME
%% REAL-DATA-LEGEND-Y          = 1.90 * HALF-FRAME
%% AVERAGE-DIRECTION-LEGEND-Y  = 1.85 * HALF-FRAME
